Abstract: The compacts carried out in the form of pastilles (of diameter 18�5 mm) according to the process of the products sintered in the presence of an abundant vitreous phase. The mixture compressed uniaxialement cold consists of an abrasive powder in Al203 and a vitreous binder containing kaolin, feldspar plagioclase and quartz . Among the constant parameters of grinding: Compactive effort, the temperature of cooking and duration period. The required characteristics are: Porosity, lifespan and the proportion of the components.
